DIEHL, DECEASED, OF NORRISTOXVN TOWNSHIP, MONTGOMERY COUNTY, PENNSYL- VANIA.

NAIL-PLATE FEEDER.

Specification of Letters Patent No. 6,291, dated April 10, 1849.

To all whom t may concern Be it known that WILLIAM Dini-IL, late of the township of Norristown, county of Montgomery, and State of Pennsylvania, deceased, did in his lifetime invent a new and useful machine to be used for and by him called a Nail-Feeder, and we, HAN- NAH DIEHL and CHARLES M. DIEHL, adw ministrators of the estate of said VILLIAM DIEHL, do hereby declare the folle-wing to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, whereof Figure l is a side elevation, Fig. 2, a horizontal top view; Fig. 3 a vertical `cross section, through as Fig. I, and Fig. 4, is a vertical section through y y Fig. l.

The purpose of this invention is to feed the strips of nail plate from which cut nails are to be formed to the machine which is to cut and form the nails. This operation of feeding the plate to the machine is now generally performed by hand and consequently every nail machine requires one person to attend it, while by the aid of this invention a single person can attend several machines, and a person of less strength will be required to attend the machines, than would be demanded to work a single machine in the ordinary way.

The following description will make known the arrangement of parts in this maL chine.

The letters in Figs. l and 2, refer to corresponding parts.

A is the base or lower bar of the frame to rest on any suitable bench, and of a length not less than twice that of the nail plate to be cut.

D and E are two posts fixed upon the base A and supporting the slide bars B, B, Fig. 2, between which slides the ratchet bar Q, connected with the upright F the obejct of which is to push forward the turning pincers m. Nearly midway between the posts D and E is a third post C, of larger dimensions than either of the others. ln this post is placed the machinery which turns the nippers.

P, Fig. l, is a toothed wheel, (also seen in Figs. 3 and 4). The axle o-f this wheel lies in the direction of the length of the machine, and is constructed as seen at a Fig. 4, with a spring click s, falling into oifsets on the two opposite sides of the axle and allowing the wheel P to turn in one direction without carrying the axle around with it, but compelling the axle to turn with the wheel when the wheel is turned in a direction opposite to the rst. Upon the saine axle a. and outside of the post C is a second oset or shoulder wheel 0, Figs. l and 3, having a spring r to stop the axis when the wheel P revolves by itself. The wheel P is moved by the rack arc H. In the axle a` is a square hole through which passes the square bar of the turning pincers m, with so much freedom as to allow it to slide easily backward and forward.

The post D, has a slot through which passes the square bar m without contact or impediment. The main lever G, is connected by a pivot with the connecting rod n, and through that with the nail machine. The pivot n is movable to different holes along` the lengt-h of Gr, in order to adjust the range of movement of the rack arc H to the extent of motion of any given nail machine. The range of movement of H must be such as to give the wheel P just half a revolution at every movement backward or forward of the main lever arm G. so that the pincers mi may be turned half round at every stroke ofthe nail machine. The rod of the pince-rs mpasses through an upright F, within which it moves on a cylindrical neck or bearing, and in the rear of F, is a screw and washer to retain the rod and enable the operator to draw it backward away from the shears when the piece of plate has been cut up and a fresh piece is to be supplied. To do this the operator draws F away from the shears, the ratchet bar G sliding readily backward und-er the clicks or claws J and K on bars now to be described.

The bar J leading to and acting on the ratchet bar Q is attached to the main lever G by a piece y. This bar J has a long slot e through which passes the piece f that gives motion to the bar J but imparts Ato it only a part of the motion of the main lever Gr. At one extremity of its movement it pushes backward a short distance the ratchet Q, so as to allow the plate, by retreating a little out of co-ntact with the cutting bench and shears, to turn over and be ready for the next cut; and at the other extremity of its movement it raises the catch lever K, and

allows the ratchet Q the support F and the pincers m to be urged up toward the shear bench by the Weight WV. The bar J passes under the arm g of the spring R, and over the head 'of the lever K, Which lever is acted upon by the spring L. A barbv c near the claW end of J raises, when drawn backward, the click or catch on the lever K out of its notch on Q, so that the Weight W acting over the pulley S then pushes the lstrip of nail plate against the stop or bench of the shears when it is ready to be cut.

The upright 0l supports the pivot of the main lever G The machine .may be put up in a small space, the turning pincers m to be level of course With the point of the nail cutter and When connected With it, must of necessity take back the nail plate by the lever J, turn it by the rack Wheel P, and, by the Weight draw it up again to the cutter, thus Working precisely as fast as the nail machine is driven and Working as perfectly and as exactly as. one of the parts of the nail machine itself and enabling a mere boy to attend several of the nail machines, the only labor being to put in the nail plates.

The plan of making the machine, above laid down is not intended to convey the idea that it is the only Way in which it can be done. The inventor himself made the machine in different Ways. This Was selected for description only as occupying less space than other methods.

Having thus fully described the machine -or nail feeder, What We claim as the inven- HANNAH DIEHL, CHARLES M. DIEHL, Aclmz'm'slmtors of the estate of William Diehl, cleceasecl.
